Introduction
The Types 670, 671, 674 and 675 panel-mounted loading regulators (Figures 1, 2, 3 and 6) are compact, rugged units used primarily for manually loading pressure-balanced gas regulators and providing manual control for diaphragm actuator control valves. Applications include remote control of gas pressure to burners in refineries, power plants and various process furnaces. The Types 670 and 675 units use the Type 67CR or 67CFR pressure regulator, the Type 671 unit uses the Type 912 pressure regulator and the Type 674 unit uses the Type 1301F pressure regulator.
Three basic panels are available within the product line as shown in Figures 1 and 6, each having one pressure regulator connected to one or two gauges
or two gauges and a changeover valve. A single gauge typically shows loading pressure to the control valve. With two gauges, one gauge shows the loading pressure and the other gauge can be connected to show downstream control pressure or any other pressure up to 300 psig / 20.7 bar. Manual backup of pneumatic controllers can be handled with those 670 Series units having a changeover valve. With it the operator selects either the automatic controller output (displayed on one gauge) or the manual loader output (displayed on the other gauge and adjusted by the handwheel) as the signal to the control valve actuator.

Operating Influences(2)
670 Series: As shown in Figure 4, output pressure changes less than 5 psig / 0.34 bar when the input pressure changes between 20 to 140 psig / 1.4 to 9.7 bar
Type 671: As shown in Figure 5, output pressure changes less than 1 in. w.c. / 2 mbar when the input pressure changes between 20 to 140 psig / 1.4 and 9.7 bar
Regulator Flow Capacity
See appropriate pressure regulator bulletin
Internal Relief for Pressure Regulators
Adequate for relieving only minor build-up situations. Refer to the appropriate pressure regulator bulletin to determine if external relief is required.
1. These pressure ranges are recommended, but all springs used in the Type 67CR or 67CFR regulators can be adjusted down to 0 psig / 0 bar. 2. Defined in ISA Standard S51.1-1979.

Features
?Control Flexibility--With a changeover valve, the operator can deliver pressure to the control valve from the manual loader, a controller or bypass the panel completely.
?Gauge Identification--Big, clear, white-on-black labels (see Figure 1) show gauge function and units at a glance.
?Convenient Fingertip Control--Turn the panelmounted handwheel clockwise to increase or counterclockwise to decrease pressure to the control valve while watching the high visibility black-on-white gauges.
?Easy Connections--Unit comes with all the hardware necessary to connect the loading pressure gauge to the pressure regulator.
?Versatility--Pressure regulators are suitable for a variety of gaseous fluids including natural gas, propane and air.
?Compact Size--The slim profiles of the regulators are ideal for installations where space behind the panel is limited.
